The veil between heaven and earth was always rent or lifted. The shadows of this world, the radiance of heaven, and the glare of hell mixed and mingled until man became uncertain as to which country he really inhabited. Man dwelt in an unreal world. He mistook his ideas, his dream, for real things. His fears became terrible and malicious monsters. He lived in the midst of furies and fairies, nymphs and naiads, goblins and ghosts, witches and wizards, sprites and spooks, deities and devils. The obscure and gloomy depths were filled with claw and wing--with beak and hoof--with leering look and sneering mouths--with the malice of deformity--with the cunning of hatred, and with all the slimy forms that fear can draw and paint upon the shadowy canvas of the dark. It is enough to make one almost insane with pity to think what man in the long night has suffered: of the tortures he has endured, surrounded, as he supposed, by malignant powers and clutched by the fierce phantoms of the air. No wonder that he fell upon his trembling knees--that he built altars and reddened them even with his own blood. No wonder that he implored ignorant priests and impudent magicians for aid. No wonder that he crawled groveling in the dust to the temple's door, and there, in the insanity of despair, besought the deaf gods to hear his bitter cry of agony and fear. The savage as he emerges from a state of barbarism, gradually loses faith in his idols of wood and stone, and in their place puts a multitude of spirits. As he advances in knowledge, he generally discards the petty spirits, and in their stead believes in one, whom he supposes to be infinite and supreme. Supposing this great spirit to be superior to nature, he offers worship or flattery in exchange for assistance. At last, finding that he obtains no aid from this supposed deity--finding that every search after the absolute must of necessity end in failure--finding that man cannot by any possibility conceive of the conditionless--he begins to investigate the facts by which he is surrounded, and to depend upon himself.
